Yep, they know how to treat vampires in Bulgaria

Now it's a scientific fact:

Archaeologists in Bulgaria say they've found two medieval skeletons pierced through the chest with iron rods intended to stop them from turning into vampires.

The discovery highlights a pagan practice common in some villages until a century ago, historians said, where people considered evil had their hearts impaled after death for fear they would return to feast on human blood.

The whys of the matter are simple:

People believed the rod would pin the dead into their graves to prevent them from rising at midnight and terrorizing the living...

And before you look down at the practice and start yakking about superstition, consider the proven scientifically fact that the remedy worked: no one of the suspects rose at midnight.

So there.
